Scheduled export/charge returning to eco mode

Am I right in saying that if you set a window for export or charge that during that time eco mode is ignored until the window passes, even if the SOC condition is reached?

As I’ve been testing timed exports with a desired % drain. The battery reached that percentage but didn’t return to powering my house until the time of the end of window. Is that the same for charging?

And how can I force it to return to eco mode operation?

I was watching my AIO, it reached the charge and I couldn’t figure out how to force it back into supporting the house. Eco mode appeared on, I tried changing the time window but it remained paused.

Have a look at the power graph and then post the result here.
We will the be able to see how the power flow over time.

Also what desired % drain are you setting?

I would have thought that, if you are intending to export down to say 30%, that any more energy in the battery must go into the house and that the battery will effectively be working in Eco mode. But let’s see your Power Graph first.

the short answer is yes, this is by design

think of it in terms of:

  • set the inverter to discharge mode from [start] to [end] time
  • set a lower SoC limit to the discharge of [limit]
  • house load take precedence, any discharge above house load is exported

So until the end time is reached the inverter won’t swap to Eco mode. Equally if your inverter reaches the limit before the end time is reached then any house load is met by grid import.
This is entirely logical (if maybe not what you intended), you told the inverter to not let the SoC drop below the limit you set in the time period so the only way for house load to be met is from grid import.

The only mitigation to this is to either not set a SoC limit or to set the end (or start) time such that it doesn’t hit the SoC limit before the end time.

Same with grid charging but since you are charging at what is presumably a cheaper rate this is usually less of an issue

Thanks. Rbor. That’s what I thought. How about charging. If I tell it to charge from 1-3am. And it hits 100% by 2:30, will it serve the house or wait until 3am before resuming normal service.

Yes, I think charging works the same way.

I haven’t manually charged/discharged for a long time now as I have predbat doing everything for me!
A future project for you.

I have an AC3.0 and I remember that a charge automatically went to Eco when the charge period finished.

But a discharge didn’t and I always had to select Eco manually at the end of a discharge period. I used to set an alarm to remind me!

I think that more recent inverters allow mote charging and discharging slots to be set.

if you program a charge from 1-3am then the inverter will charge the battery and hold the battery at 100% until 3am. If it hits 100% at 2:30 then the charge instruction still is in operation and the battery won’t start discharging until 3am.

Is there anyway to override this and have it resume discharging?

I would love to have home asssistant monitor and when it hits the target wait a beat and then instruct it to resume eco mode type operations.

If you have Home Assistant and givtcp running then setting select.givtcp_xxxx_charge_end_time_slot_1 to ‘now’ (in hh:mm:00) format should be all you need to do to stop the charging
